mm: add comments for allocation helpers explaining why they are macros
A number of allocation helper functions were converted into macros to
account them at the call sites. Add a comment for each converted
allocation helper explaining why it has to be a macro and why we typecast
the return value wherever required. The patch also moves
acpi_os_acquire_object() closer to other allocation helpers to group them
together under the same comment. The patch has no functional changes.
